What size socket for Torx bolts on 172 gearbox?

As above, what size socket do I need for the external Torx bolts that secure the bell housing to the block?

Didnt think there was any? There all either 18mm or 13mm iirc?

the only ones are to split the gear casing from the bell housing (e10 iirc)

But you don't need to touch them to remove a box ben

There's a leak from somehwhere and the only evident oil is on the join betwen the bell housing and the block.

I was hoping a quick nip on each bolt may cure it?

By the way Benjamin, I've been meaning to ask you for a while, have you swapped the pimp wagon for the Evo' in you profile? I'm fancying an 8 after Christmas.
